MOVE LIGHT SOURCE

 

Description: DSI uses two types of light sources:  ambient light and directional light.

 

Ambient light comes from all directions and illuminates objects regardless of their position or orientation with the same intensity.

 

Directional light comes from a specific direction.  It flows uniformly and maintains a consistent intensity.  It has a directional vector that determines the face on which an object receives light.

 

The MOVE LIGHT SOURCE command positions a directional vector at two points that are perpendicular to an object.  The right and left arrow keys move the light source in the positive and negative X-direction, while the up and down arrow keys move the light source in the positive and negative Y-direction.
